Trump on Thursday fired back after President Obama said world leaders are “rattled” by Trump and accused the presumptive GOP presidential nominee of being ignorant on world affairs.

“When you rattle someone, that’s good,” Trump said at a press conference in Bismarck, N.D.
“Many of the countries in our world have been absolutely abusing us and taking advantage of us. … If they’re rattled in a friendly way, that’s a good thing, not a bad thing.”
